 ### Password Policy
 
+:::warning
+By default, authentik's Password policy is compliant with [NIST's recommendations](https://pages.nist.gov/800-63-4/sp800-63b.html#password) for passwords. To remain compliant with NIST, be cautious when editing the default values. For additional hardening configuration settings, refer to [Hardening authentik](../../security/security-hardening.md#password-policy).
+:::

 This policy allows you to specify password rules, such as length and required characters.
 The following rules can be set:

 While authentik is secure out of the box, you can take steps to further increase the security of an authentik instance. As everyone knows, there is a consequential tradeoff between security and convenience. All of these hardening practices have an impact on the user experience and should only be applied knowing this tradeoff.
 
+### Password policy
+
+authentik's default Password policy complies with the [NIST SP 800-63 Digital Identity Guidelines](https://pages.nist.gov/800-63-4/sp800-63b.html#password).
+
+However, for further hardening compliant to the NIST Guidelines, consider
+
+-   setting the length of the password to a minimum of 15 characters, and
+-   enabling the "Check haveibeenpwned.com" blocklist comparison (note that this cannot be used on Air-gapped instances)
+
+For further options, see [Password policy](../customize/policies/index.md#password-policy).
+
 ### Expressions
 
 [Expressions](../customize/policies/expression.mdx) allow super-users and other highly privileged users to create custom logic within authentik to modify its behaviour. Editing/creating these expressions is, by default, limited to super-users and any related events are fully logged.
